Abstract
Provided is a parasitic cycle work-done method and a parasitic cycle engine in the engine technique field. The work-done method supplies the air for the engine with the high temperature heat source, the air is elevated temperature owing to compression after the engine sucks the high temperature air, the water is sprayed before the end of the compression, the water forms steam after the water absorbs the heat, the steam expands so as to push the piston for work-done, then the air is discharged, four processes of entering high temperature air, compressing and spraying water, expanding the steam and working and discharging air are formed and repeated, the work cycle is formed. The intake passage of the parasitic cycle engine is communicated with the heat source, the working chamber has a sprinkling machine for sprinkling the working chamber, the power take-off shaft of the parasitic cycle engine drives the generating system, so the generating system is integrated, for example, the energy of the tail gas of the internal combustion engine is transformed electric energy. The parasitic cycle work-done method doesn't need the combustion process, which recoveries the tail gas energy abundantly, and reduces the compression negative work of the engine via heat absorption of steam. The parasitic cycle engine has projecting ascendancy on the energy conservation side.
Description
Technical field
A kind of parasitic circular work method and parasitic cycle engine relate to the engine operational cycle work method and steam is done power engine, belongs to technical field of engines.
Background technique
Internal-combustion engine mainly comprises quartastroke engine, two stroke IC engine and rotor internal-combustion engine, and their work cycle all comprises air inlet, compression, burning expansion acting, four processes of exhaust.Work method is by fuel combustion process, and the mixed gas volume is expanded, thereby promotes the piston acting.Combustion process occurs in internal cavities, thereby is called as " internal-combustion engine ".The intake temperature of internal-combustion engine is generally normal temperature, and delivery temperature is very high, has a large amount of heat energy to be deflated to take away, and has influenced fuel thermal efficiency.
Be the energy that minimizing is wasted from exhaust, fuel saving, (US2002043222-A1 DE3613270-A) discloses 6-stroke IC engine to some patents for CN200510044165.X, US4736715-A.The working procedure of 6-stroke IC engine is " air inlet-compression-burning expansion acting-compression (or part exhaust)-steam expansion acting-exhaust " six strokes.This internal-combustion engine, all tail gas of compression in four-stroke that have, the compression negative work is very big; The discharge unit tail gas in four-stroke that has, the compression negative work is still bigger, and fails to make full use of exhaust heat-energy.
Utilizing aspect the steam acting, steamer has much representativeness, and fuel burns outside cylinder, makes the water in the boiler become high pressure superheated steam, and steam enters cylinder and promotes the piston acting.The fuel thermal efficiency of this motor is lower.
Summary of the invention
The objective of the invention is to disclose a kind of engine operational cycle work method that can reclaim internal-combustion engine or other heat source high temp exhaust energy, and the engine technology that utilizes this work method.
Parasitic circular work method of the present invention, it is characterized in that: utilize high temperature heat source to be the motor air feed, after motor sucks the high temperature air inlet, compress gas is further heated up, water spray before compression process finishes, immediately become steam after the water heat absorption, thereby steam expansion promotes the piston acting, carries out exhaust afterwards, forms " advancing High Temperature Gas-compression water spray-steam expansion acting-exhaust " four working procedure thus, so repeatedly, form work cycle.Such motor work method must have thermal source just can keep work cycle, thereby claims such work cycle to be parasitic circulation.
Parasitic cycle engine of the present invention, piston, pto, body, gas-entered passageway and exhaust passage are arranged, construct the working room by piston and body, gas-entered passageway and exhaust passage and working room join, it is characterized in that: engine intake passage is connected with thermal source, the water jetting apparatus of water spray in the oriented working room, the work cycle of motor is " advancing High Temperature Gas-compression water spray-steam expansion acting-exhaust " four working procedure.Water spray is located at before the Piston Compression top dead center constantly, and injection flow rate under various operating modes and water spray all will accurately be controlled constantly.Parasitic cycle engine can be divided into the parasitic cycle engine of four-stroke, the parasitic cycle engine of two-stroke and the parasitic cycle engine of rotor.Drive power generation system with parasitic cycle engine pto, be integrated into parasitic circulating generator, be specially adapted to be connected on the internal-combustion engine vent-pipe, the exhaust gases of internal combustion engines energy is become electric energy.
Compare with conventional internal combustion engine circular work method, parasitic circular work method of the present invention does not need combustion process, thereby does not need to provide fuel for parasitic cycle engine; Compare with 6-stroke IC engine, parasitic cycle engine has more the advantage of abundant recovery exhaust energy; Compare with steam engine, the used steam of parasitic cycle engine results from inside, working room, non-preparation in advance, thereby can be by the compression negative work of water vapor heat absorption minimizing motor.Parasitic cycle engine has outstanding advantage aspect energy-conservation.
